Abstract

This report had as purpose evaluate the development of cultivation of tilapia Oreochromis niloticus lineage Chitralada in tanks-net, observing patterns of growth rate, surviving rate, weight and mass of tilapias, and related to the commercial utilization. For the study were used ten tanks-net a public dam Boqueirão do Cais, in Cuité, state of Paraíba (PB). The process of cultivation lasted 304 days, receiving specialized technical surveillance, monitoring the physical and chemical patterns of water, also observing stages of feeding, of growth rate, weight and mass of tilapias.
